Over time, portable handheld devices are expected to become more powerful and thus require higher speed signaling interfaces between their internal components. These future handheld devices will require interfaces that operate at 10X to 100X faster data rates (e.g. one to ten gigabits per second). Unfortunately, existing electrical multi-gigabit signaling interfaces (such as CML or LVDS) consume too much power to be efficiently used in mobile platforms. Our research is focused on the development of a physical interface, including driver and receiver circuits that reduce power consumption by 10X over present state-of-the-art. In addition, our interface reduces electromagnetic emissions leading to reduced EMI – an important consideration in mobile platforms. Together, reduced power consumption and lower electromagnetic emissions make our approach better suited for future portable devices than existing methods.
